During the progress of any fire within the city limits, fire fighters and police officers, the fire chief (or in case of his absence or disability, the person in command of the department) shall have complete control of the scene of such fire, and the vicinity thereof, to such a distance in every direction as shall be necessary to enable him to effectively fight the fire. All fire fighters and police officers shall obey all lawful orders given them by the commander. He may likewise disperse crowds, rope off streets, buildings or other places within the city limits, destroy buildings or other property and take any other steps which may appear necessary in extinguishing a fire and in preventing looting, rioting or other disorder. It shall be the duty of all citizens, at his request, to render him all lawful assistance therein. No person shall interfere in any way with the fire chief, or with any person acting under the orders of the fire chief or acting fire chief while in the discharge of their duties. (Ord. O-10-93 § 4 (part), 1993; prior code § 2-3-24)
